带有 JAXB 编组器的 MarshallingWebServiceOutboundGateway 抛出错误

Question

我正在使用 spring-integration 4.1.2-RELEASE，MarshallingWebServiceOutboundGateway 有点问题。我正在尝试对 SOAP Web 服务进行 SOAP 调用，使用 JAXB 生成 wsdl 的对象表示。

我的自动接线和流程如下所示：

@Autowired
MarshallingWebServiceOutboundGateway securityService;

@Autowired
HttpRequestExecutingMessageHandler documentService;

@Bean
IntegrationFlow getDocument() {
    return IntegrationFlows.from("entryPointChannel")
            .handle(securityService)
            .handle(documentService)
            .get();
}

问题出在 securityService bean 上。这是定义：

@Value("${evry.services.security.endpoint}")
String securityEndpoint;
@Value("${org.apache.ws.security.crypto.merlin.keystore.alias}")
String user;
@Value("${org.apache.ws.security.crypto.merlin.keystore.password}")
String password;

@Bean
MarshallingWebServiceOutboundGateway securityService() {
    Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
    marshaller.setContextPath("securityServices.wsdl");
    MarshallingWebServiceOutboundGateway securityGateway = new MarshallingWebServiceOutboundGateway(
            securityEndpoint, marshaller, marshaller
    );

    Wss4jSecurityInterceptor securityInterceptor = new Wss4jSecurityInterceptor();
    try {
        securityInterceptor.setSecurementSignatureCrypto(new CryptoFactoryBean().getObject());
    } catch (Exception e) {
        e.printStackTrace();
    }
    securityInterceptor.setSecurementActions("Timestamp Signature");
    securityInterceptor.setSecurementSignatureKeyIdentifier("DirectReference");
    securityInterceptor.setSecurementSignatureUser(user);
    securityInterceptor.setSecurementPassword(password);
    securityInterceptor.setSecurementTimeToLive(300000);
    securityInterceptor.setTimestampPrecisionInMilliseconds(true);

    securityGateway.setInterceptors(securityInterceptor);


    return securityGateway;
}

调用时，这是（部分）错误输出：

javax.xml.bind.JAXBException: class org.springframework.util.LinkedMultiValueMap nor any of its super class is known to this context.
    at com.sun.xml.internal.bind.v2.runtime.JAXBContextImpl.getBeanInfo(JAXBContextImpl.java:567)
    at com.sun.xml.internal.bind.v2.runtime.XMLSerializer.childAsRoot(XMLSerializer.java:467)
    at com.sun.xml.internal.bind.v2.runtime.MarshallerImpl.write(MarshallerImpl.java:308)
    at com.sun.xml.internal.bind.v2.runtime.MarshallerImpl.marshal(MarshallerImpl.java:236)

在我看来，spring-集成框架以某种方式破坏了 JAXB 期望的响应类型，但我不知道如何解决这个问题。有人可以帮忙吗？

Answer 1

这是我考虑不周的情况。我需要在 MarshallingWebServiceOutboundGateway 前面有一个转换器，以将来自 entryPointChannel 的 LinkedMultiValueMap 转换为 JAXB 编组器所期望的对象。
